Rated 5 out of 5 by from Great sound and volume! I received my Under Armour JBL Sport Wireless Flex Headphones the other day and I've got to say I'm impressed! They're lightweight, easy to use and the sound quality is excellent. I've found other headphones to be lacking in the sound dept., requiring that I have to keep them in the max volume position - but I was surprised that these headphones allowed me to listen to my workout music at the halfway mark! This is a luxury I've never before experienced. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Headphones for daily wear AND for your workout I normally listen to podcasts and music while running. While I have owned bluetooth headphones before, they rarely last long enough to get me through a long run. This makes them quite convenient for my weekday runs, but always forced me to use wired headphones for those long weekend workouts. I was a bit skeptical when I read the promise of a 12 hour battery life on the UA Sport Wireless Flex headphones and I am very grateful to be given the opportunity to review them. The headphones feel well built and have a satin texture on the neck piece. This textured finish helps while working out, as it stops them from slipping around on your neck. The ear-buds are magnetic and you can join them together to keep them from flopping about when not in use. Great touch. They are slightly flexible and can be molded around your neck easily. I honestly forget that I’m wearing then during the day. The buttons are easy to find with raised textured icons for play, pausing, plus and minus for the volume. They are pretty intuitive and you can easily get going without reading the manual. The only thing that you’ll need to read to figure out is how to turn on my favorite feature on them… the flashing LED light on the back of the neck piece. This is a seriously bright light, which helps for visibility when running at night. Not blindingly bright, but plenty to keep you from being invisible. Great design overall. As far as the charging and battery life… I can generally charge them fully in about 30 minutes and I have yet to kill the battery. I use them all day during work and go straight from there into a workout without any issues. I seriously think that they would outlast my phone and I have no reason to doubt the claimed 12 hours. The only thing I would add would be an indicator of the remaining battery life. Who knows, maybe the bluetoot light changes colors when the battery is close to dying, but again I haven’t even been close to killing the battery to know. As a whole, these are seriously brilliant headphones, with the great sound that you can always expect from JBL products. These would be a great choice for anyone wanting sturdy headphones that will survive a workout and don’t look out of place for daily use. Great product overall.

Rated 1 out of 5 by from Waste of $ Agree with person below who noted it won't hold a connection to Android phone. Extremely annoying, as I'm on the phone a lot for work. I tried working with customer service, who advised "fixes" such as avoiding my router, walls, and open spaces. I was too busy to deal with this within the 30-day return window, so was offered a different model with fewer features, which they won't send until they receive the current headset back. This means I'll have to buy a new one for work anyway to get me through the 4-week return window. This is way more expensive than most headsets out there--a huge disappointment and waste of money.

Rated 5 out of 5 by from Excellent sound great for my work outs I received these 3 days ago and I am amazed by the sound quality,I own a pair of beats and the sound quality of the Ua sports flex was about the same as my beats . Great for work outs did not have problem with ear buds falling out while exercising. Connected to Bluetooth quickly and have had no problem with Bluetooth connectivity. Has a long lasting battery I am very satisfied with this product keep up the good work [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Best earbuds I’ve ever used! I’ve tried a ton of earbuds in my day (a lot). And these have been by far the best in terms of sound quality. The noise canceling on these is absurd, and all in all great construction and comfort. My job requires me to move in a very high paced manner and these have been perfect. Staying in place and never falling out. Definitely better than the red and black “b” brand that are overpriced. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from The headset that lasts forever These headphones are pretty much an a+ product. The only reason I have it 4 stars is because if you see listening to anything that bumps, you won't get much of a bump but other than that comfort is a 10, the led light is a cool different feature and would def help anyone be seen in a dark area, the buttons are some you won't be accidentally pressing at any point, the mic is excellent quality and finally the battery is amazing , I got 12 hours use before I had to charge it again and it charged in less than an hour. Great product. [This review was collected as part of a promotion.]

Asked by: mkcmax
Hi there, the light indicators can't be disabled as they're built in and is a permanent feature of the product.

I purchased my first pair a little over a month ago. Within the first 2 weeks they stopped charging, luckily I was able to exchange this pair in store. No big deal, things happen. Fast forward 3 more weeks and pair #2 stopped charging. Any thoughts?

I'm beyond frustrated. Nearly every time I pause what I am listening to I have trouble reconnecting. It connects fine in the morning when I first turn it on. Then most other times I have to turn it off, then turn it back on 2x to pair up and start again

Asked by: stonewals
Hello! No, it does not vibrate on incoming calls.&nbsp;But you can do phone calls with the JBL UA Sport Wireless Flex. You can answer and disconnect phone calls by pressing on the Play/Pause button.
